Posters with the bold headline “IMMIGRANTS WELCOME” above an image of barbed wire being severed with a wire cutter were displayed in hallways and classrooms at River Road/El Camino del Rio Elementary School in Eugene, Oregon, KLCC-FM reported.

Eugene School District officials said they believe a contractor took down all the posters over winter break, KLCC reported.

“It wasn’t the ‘IMMIGRANTS WELCOME,’ it was what was below that, that spoke about the border wall and that was where it gets a little bit tricky with the politics of it all,” District Superintendent Gustavo Balderas told the station, adding that some teachers have replaced the original posters.

Kristidel McGregor’s children — who speak English at home — attend River Road/El Camino del Río, and McGregor wrote an op-ed defending the posters.

“Many of the students at El Camino del Rio, or their parents or siblings, have immigrated to the United States,” she wrote.
